That's the wire that goes to the back of the alternator. The tab is embedded in the wiring harness.

oneZ11.....Do you have an AIM? If not, then you need to get one and examine it front to back until you nearly know it by heart. That is the first thing I did and it in turn answered numerous questions that I had about the Camaro assembly process.

A good friend saved these clips (pics) from when he worked for GM. He kept them wanting to use them on his own project. Unfortunately he had to sell his Camaro. I used the ones that worked best for me, neither of which are like the originals.

The clip in your pic is obviously a re-pop but should work fine for the fender. The problem is, the original was not offset (look at pic) but how many people actually know this. This same offset will not work for the alternator bracket. by the time you attach it to the harness and tape it, it will be too bulky to penetrate/seat properly. And, no idea on where to get the clips. I checked for several days and the only one I could come up with is the one in your pic. If you find out, let me know.

As for the color, both of them should be white/off-white. But again, sure beats the heck out of buying the entire harness, and again...who really knows .

That offset repro clip is used in the middle of the front lighting harness under the rad support. I haven't found a source for the other clips either. Probably the best bet is some used harness and take them out.
